Claims

[Scope of utility model registration request]

A collimator used in a device that images radiation from a subject to which a radioactive isotope has been administered through a collimator equipped with a large number of parallel holes and a scintillation detection unit as an image of the region of interest of the subject, and captures the image. A parallel multi-hole collimator of a scintillation camera, characterized in that a gap is provided between the collimator and the scintillation detection section, and a scattering member with a small atomic number for scattering the radiation is interposed in the gap. meter.
